Pack Performance Engineer
Battery Systems / Pack Engineering
Department: Battery Systems / Pack Engineering
Reports to: Head of Battery Systems Engineering (or Pack Engineering Lead)
Level: Senior / Staff Engineer
Location: United States (site aligned to Gotion's North America engineering footprint)
Role Summary
The Pack Performance Engineer owns the technical bridge between cell, BMS, and vehicle: defining and validating how a battery pack performs across its power boundaries, thermal envelope, and system requirements. This is a hybrid role that sits deliberately at the intersection of three disciplines — BMS/controls, systems engineering, and pack hardware/thermal — rather than living entirely inside one. You will define power and SOC/SOP limits and see them through to vehicle integration, translate performance requirements into validated system attributes, and own pack-level thermal and hardware performance from design through DVP.
Core Focus Areas
1. BMS Interface, Power Limits & Vehicle Integration
- Define battery charge/discharge current limits, combining SOC, temperature, and cell capability to establish accurate power boundaries
- Own SOC estimation and SOP (state of power) algorithm inputs and validation
- Lead cell balancing strategy and isolation measurement verification
- Drive BMS and Vehicle Control Unit (VCU) integration, ensuring pack performance data and limits are correctly interpreted at the vehicle level
- Support functional safety testing and requirements across chemistries (e.g. NCM, LFP)
- Assess the impact of production ramp, design changes, and process changes on battery system performance
2. Battery System Requirements & Performance Validation
- Translate electrified-powertrain architecture and performance targets into clear, traceable battery system requirements
- Own performance-attribute definition and specification across the battery system
- Build and maintain functional safety traceability from requirement to validation
- Lead systems-level validation planning and execution across battery systems, requirements, and vehicle integration
- Partner with powertrain, controls, and vehicle integration teams to keep requirements and validation evidence aligned
3. Pack Hardware Performance & Thermal Management
- Own pack-level performance evaluation: available power, internal resistance, and thermal performance
- Provide pack performance input into BMS configuration
- Lead battery performance testing including thermal cycling, thermal runaway characterization, and DVP (Design Verification Plan) execution
- Support custom high-voltage battery pack design, prototype build, and validation
- Own pack thermal / cooling system development, from concept through validated performance
- Analyze capacity, DCIR, cell-disconnect behavior and other pack-level performance data to inform design decisions
Required Experience & Qualifications
- Bachelor's or Master's degree in Electrical Engineering, Mechanical Engineering, or a related field
- 7+ years of experience in battery systems, BMS, or pack engineering at an EV OEM or battery systems supplier
- Hands-on experience with SOC/SOP estimation, cell balancing, and isolation measurement
- Demonstrated experience defining charge/discharge current limits and power boundaries across SOC, temperature, and cell capability
- BMS and Vehicle Control Unit (VCU) integration experience
- Experience defining battery system requirements and performance attributes, with functional safety traceability
- Experience with pack thermal design and validation — thermal cycling, thermal runaway, and DVP
- Experience with high-voltage battery pack design, prototyping, and validation
- Working familiarity with multiple cell chemistries (e.g. NCM, LFP)
- Strong cross-functional collaboration skills across systems, controls, hardware, and vehicle integration teams
